` KCl` can be used in salt bridge as an electrolyte in which of the following cells ?

A

`Zn| ZnCl_2 ||AgNO_3 |Ag`

B

`Pb|Pb(NO_3)_2 ||Cu (NO_3)_2|Cu`

C

` CU|CuSO_4||AuCl_3|Au`

D

` Fe|FeSO_4||Pb(NO_3)_2)|Pb`

Text Solution

Verified by Experts

The correct Answer is:
C
KCl can make pereiptiate with ` AgNO_3, Pb(NO_3)_2` so can`t be used along these electrolytes.
